This PC will definitely perform better for gaming than the Ryzen build. But can loose bit of gaming performance while steaming compared to Ryzen build. Ryzen build is more consistent with Fps while Streaming. Intel build is better in gaming performance.
If he games most of time and rarely Streams it go for Intel. But if he regularly Streams go for Ryzen.
